It sounds like you already have the answer and just want some reassurance. The throttle position sensor should not be " adjusted" it should be replaced. This is relatively inexpensive and simple to do. To find it just look at your throttle body, this is where you can " rev" the vehicle from under the hood, and you will find it right there!Email me and let me know how this works for you my email is janderson0574@hotmail.
